We should note that all of these places of thermal extremes (Finnish saunas, Japanese hot baths, American beaches and mountains) have their opposites close at hand. There are possibly two reasons for having the extremes right next to each other.
The first is physiological: the availability of extremes ensures that we can move from one to the other to maintain a thermal balance.
The second might be termed aesthetic: the experience of each extreme is made more acute by contrast to the other.
Works of art which have great life often have intense contrast within: rough/smooth, solid/void, loud/silent, empty/full. It is the difference between opposites which gives birth to something. Contrast is what often gives other principles their degree of life – the intensity of the boundary, the markedness of the alternating repetition.
Contrast strengthens centers by making each a deeper entity of itself, and thereby giving deeper meaning to both. It is, at its simplest, what allows us to differentiate. But meaningless contrast remains meaningless. It is only when centers are actively, mutually, and meaningfully composed that it acts to deepen the whole.
"Because this is a garden where things can be left out at night without being stolen, we're going to 'furnish' the garden with French café chairs that won't be secured in the ground, so people can move them to wherever they want to sit...It's like with the chairs being totally casual and relaxed and comfortable. They set a tone. There's things that you have to do to get the right feel, where it's all already there, but then, you know, 'Bing!' – there's a moment of recognition." The patterning of chairs pulled together in different ways by successive waves of visitors over the course of the day becomes an index of the shifting patterns of people that sit in a variety of arrangements to facilitate conversations and other intersubjective alignments, or simply to allow for a moment of private contemplation free from contact with others.
